问题描述
我可以成功地接收从我的Web服务值,以便在repect脚本工作正常。但是我现在想将数据发送到使用下面的数据字段中的Web服务。我无法弄清楚是如何发送一个简单的字符串(如测试)到Web服务,这是我的web方法需要作为一个参数。
任何帮助是非常AP preciated。例如:
函数setQuestion(){
$阿贾克斯({
键入:POST,
**数据:{},** //我如何使用它来发送一个字符串?
数据类型:JSON,
网址:HTTP:// someURL
的contentType:应用/ JSON的;字符集= UTF-8,
成功:的onSuccess
});
}
功能的onSuccess(MSG){
$(#questiontxt)追加(MSG);
}
有关ASMX你需要传递的数据对象的字符串化的版本,因此,例如:
VAR数据={参数1:+ param1IsANumber +
,参数2:\+ param2IsAString +\};
$阿贾克斯({
数据:数据,
数据类型:JSON,
网址:网址,
键入:POST,
的contentType:应用/ JSON的;字符集= UTF-8,
成功:函数(结果){}
});
或者你也可以哈瓦一个对象,并使用 jQuery的JSON的
VAR数据= {};
data.param1 = 1;
data.param2 =一些字符串;
$阿贾克斯({
数据:jQuery.toJSON(数据),
数据类型:JSON,
网址:网址,
键入:POST,
的contentType:应用/ JSON的;字符集= UTF-8,
成功:函数(结果){}
});
最后,您的Web服务类必须是这样的:
[WebService的(命名空间=http://www.somedomainname.com/)
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)
[ScriptService]
公共类为MyService:System.Web.Services.WebService
{
[WebMethod的]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)
公共无效MyServiceCall(INT参数1,字符串参数2)
{
}
}
I can successfully receive values from my web service so in that repect the script is working fine. However I am now trying to send data to the webservice using the 'data' field below. What i cant figure out is how to send a simple string (e.g. "test") to the web service which is what my web method expects as a parameter.
Any help is much appreciated. For example:
function setQuestion() {
$.ajax({
type: "POST",
**data: "{}",** //how do i use this to send a string??
dataType: "json",
url: "http://someURL",
contentType: "application/json; charset=utf-8",
success: onSuccess
});
}
function onSuccess(msg) {
$("#questiontxt").append(msg);
}
For asmx you need to pass a stringified version of the data object, so for example:
var data = "{param1:" + param1IsANumber +
", param2:\"" + param2IsAString + "\"}";
$.ajax({
data: data,
dataType: "json",
url: url,
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (result) {}
});
Or you can hava an object and use jquery-json
var data = {};
data.param1 = 1;
data.param2 = "some string";
$.ajax({
data: jQuery.toJSON(data),
dataType: "json",
url: url,
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (result) {}
});
Finally, your web service class must look like:
[WebService(Namespace = "http://www.somedomainname.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class MyService : System.Web.Services.WebService
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void MyServiceCall(int param1, string param2)
{
}
}
